  • Publication number: 20240075718
    Abstract: The invention provides a laminate having a protective film release auxiliary tape and comprising a rigid temporary support body (inorganic substrate) and a polymer film provided with a protective film. The laminate is configured such that the protective film can be peeled from the polymer film without separating the polymer film from the temporary support body. The laminate comprises an inorganic substrate, a heat-resistant polymer film, a protective film, and a protective film release auxiliary tape in this order. The adhesion strength F1 according to a 90 degree peeling method between the inorganic substrate and the heat-resistant polymer film, the adhesion strength F2 according to a 90 degree peeling method between the heat-resistant polymer film and the protective film, and the adhesion strength F3 according to a 90 degree peeling method between the protective film and the protective film release auxiliary tape satisfy the relationship F3>F1>F2.

  • Patent number: 11035643
    Abstract: A barrel catch of a toy gun has a barrel through hole with diameter larger than outer circumference of the barrel so that the barrel penetrates through hole center. The barrel catch includes a barrel fitting portion fitted/attached to the barrel on the inner circumference of the hole opposite to the pressing portion exposed from an opening in a barrel attachment portion of a toy gun body. The barrel catch is housed in a housing portion of the toy gun body slidably in the direction defined by the pressing portion and the opposite portion of the pressing portion. The barrel includes a barrel catch fitting portion fittable to the barrel fitting portion of the barrel catch upon penetration of the barrel through the barrel catch. The barrel slidably penetrates the barrel through hole of the barrel catch in the direction defined by the pressing portion and the opposite portion.

  • Patent number: 10866058
    Abstract: A device for attachment-detachment of a slide for toy gun only by operating a single lever without using any tool, includes a toy gun body, a slide at an upper part of the toy gun body while covering a barrel, and slidingly movable in directions toward the barrel and rear side of the toy gun, a takedown lever disposed on the toy gun body surface at a boundary with the slide, and rotatingly movable along the toy gun body surface, and a slide block crank that comes in contact with a slide block abutment portion of a shaft support portion of the slide to prevent the slide from moving toward the rear end side, and moves in muzzle/non-muzzle directions accompanying with the rotating motion of the takedown lever. The slide block crank extends closer to a muzzle in moving in the muzzle direction than in moving in the non-muzzle direction.
